Summary:

The American Community Survey (ACS) is a part of the
Decennial Census Program, and is designed to produce critical
information about the characteristics of local communities. The ACS
publishes social, housing, and economic characteristics for
demographic groups covering a broad spectrum of geographic areas in
the United States and Puerto Rico. Every year the ACS supports the
release of single-year estimates for geographic areas with populations
of 65,000 or more. Demographic variables include se... (more info)

The American Community Survey (ACS) is a part of the
Decennial Census Program, and is designed to produce critical
information about the characteristics of local communities. The ACS
publishes social, housing, and economic characteristics for
demographic groups covering a broad spectrum of geographic areas in
the United States and Puerto Rico. Every year the ACS supports the
release of single-year estimates for geographic areas with populations
of 65,000 or more. Demographic variables include sex, age,
relationship, households by type, race, and Hispanic origin. Social
characteristics variables include school enrollment, educational
attainment, marital status, fertility, grandparents caring for
children, veteran status, disability status, residence one year ago,
place of birth, U.S. citizenship status, year of entry, world region
of birth of foreign born, language spoken at home, and ancestry.
Variables focusing on economic characteristics include employment
status, commuting to work, occupation, industry, class of worker,
income and benefits, and poverty status. Variables focusing on housing
characteristics include occupancy, units in structure, year structure
built, number of rooms, number of bedrooms, housing tenure, year
householder moved into unit, vehicles available, house heating fuel,
utility costs, occupants per room, housing value, and mortgage status.
The American Community Survey is conducted under the authority of
Title 13, United States Code, Sections 141 and 193, and response is
mandatory.

Universe:
All persons and housing units in the United States
including Puerto Rico.

Data Types:
survey data

Data Collection Notes:

Parts 103 and 104 represent, respectively, the
entire United States Housing and Population datasets for the 2005
American Community Survey (ACS). Both parts 103 and 104 are quite
large and should be downloaded at the discretion of the user.

Any state's housing and population data
files can be merged via the variable SERIALNO to create a hierarchical
data file. The hierarchical data structure represents the responses of
all individuals reported living in a given housing unit. Individuals
can be distinguished by the variable SPORDER (Person Number). If users
are merging files, keep in mind that estimates of family, household,
and housing characteristics will make use of the housing weights.
Estimates of person characteristics will use the person weights.

Users are strongly encouraged to read all documentation regarding
sampling errors and weights prior to merging files. Documentation is
available for download or can be accessed on the
American Community Survey Web
site.

Methodology

Weight:
The data in the household and population files contain
weights. The initial weights reflect the probability of selection
and are adjusted for interviewed households to account for
noninterviews. Additional weights reflect independent housing unit
and population estimates.

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:
